US 2023/0422141 A1 · RELAY DEVICE MANAGEMENT WITH MULTIPLE QUALITY THRESHOLDS

Abstract

A remote user equipment (UE) device manages relay reselection using a plurality of quality thresholds. In one example, when a current communication route from the remote UE device to a communication device through a first relay UE device includes a first sidelink PCS link that has quality less than a preferred quality threshold, the remote UE device evaluates candidate relay UE devices. The remote UE device selects the second relay UE device where the candidate relay UE device provides a communication route with a second sidelink PCS link with a quality greater than the preferred quality threshold and where the quality of the first sidelink PCS link is below a minimum quality threshold and the second sidelink PCS link has a quality above the minimum quality threshold. Otherwise, the remote UE device continues to communicate over the first communication route through the first relay UE device.

Dependent claims

A remote user equipment (UE) device comprising:

a transceiver configured to communicate over a first communication route from a remote UE device to a communication device through a first UE relay device, the first communication route comprising a first sidelink communication link from the remote UE device to the first UE relay device;
and
a controller configured to, in response to determining that a first quality of the first sidelink communication link is below a preferred quality threshold, determine a second quality of a second sidelink communication link from the remote UE device to a second relay UE device and to determine whether the second relay UE device should be selected for communication with the communication device based on an evaluation of the first quality and the second quality relative to the preferred quality threshold and to a minimum quality threshold, the preferred quality threshold greater than the minimum quality threshold,
the transceiver configured to, when the second relay UE device is selected for communication with the communication device, communicate over a second communication route to the communication device through the second UE relay device, the second communication route comprising the second sidelink communication link.
